> Currently, we are using hive.default.fileformat for specifying the default file format in CREATE TABLE statement. Multiple issues exist:
> - This parameter value is not from `hive-site.xml`. Thus, even if users change the hive.default.fileformat in `hive-site.xml`, Spark will ignore it. To change the parameter values, users have to use Spark interface, (e.g., by a SET command or API). 
> - This parameter is not documented. 
> - This parameter value will not be sent to Hive metastore. It is being used by Spark internals when processing CREATE TABLE statement. 
> - This parameter is case sensitive. 
> Since this is being used by Spark only, it does not make sense to use a parameter starting from `hive`. we might follow the other Hive-related parameters and introduce a new Spark parameter here. It should be public. Thus, how about replacing `hive.default.fileformat` by `spark.sql.default.fileformat`. we also should make it case insensitive.
